3 Claims.

This invention pertains to door locks, and more particularly to a systemof locks for'a plurality of doors in pleasure vehicles.

At the present time, vehicle doors `are controlled .5 and latchedindependently, and have inner and outer latch operating handles.Consequently, there is continual danger of'accidental opening by theldoors by the passengers, particularly children, when the vehicle is inmotion.

It is, therefore, the primary object of the present invention to providea plurality of positive locks for the several doors of a. motor vehicle.in combination with a remote actuating mechanism conveniently locatedwithin control'of the operator only, whereby a plurality of doors can besimultaneously released or locked to prevent either accidental orunauthorized opening.

Incidental to the foregoing, a more specific object of the inventionresides in the novel construction of the positive lock employed.

With these and other objects in view, the invention. consists in thenovel construction, arrangement, and formation of parts', as will behereinafter more specifically described, claimed and illustrated intheaccompanying drawing, in

which drawing:

Figure 1 is a. fragmentary longitudinal section through a motor vehicleequipped with the present invention, the same being taken on line I-I ofFigure 2 is" a plan. s

v, line 2-2 of Figure 1.

' Figure 3 is an enlarged, fragmentary detail view, with parts brokenaway and in section to more lclearly illustrate structural features, thesame being taken on the line 3--3 of Figure 2.

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure3.

. Figure 5 is a similar view showing the lockin its retracted position.

.Figure 6 is a fragmentary detail view of the actuating mechanism takenon the line 6-4 of Figure 1 l Y Referring now more particularly to theaccompanying drawing, the numeral I designates a conventional closedbody of a motor vehicle provided with front and rear doors 2 and 3,respectively, which close and latch against intermediate 'posts 4 in theusual manner..

As best shown in Figures 3 to 5, inclusive, the posts 4, which areformed of metal, are hollow and have secured therein lock housings 5,which contain mechanism vhereinafter describedI for positively lockingthe adjacent door. or doors.

Mounted upon the dash Ii in front of the driver ectional view taken onthe end'thereof iiexible operating wires I0.

' of the slide plates I8 and I9.

or at any other convenient point is a manipulatinghandle l Secured upona rock shaft 8 extending through the dash. A crank-arm 9l is rigidlysecured to the inner end of the rock shaft, and has secured to theopposite sides of the lower 5 These wires lead in opposite directionstoward the side walls of the vehicle body. Guide tubing I I slid. ablyreceives the wires, and the tubing il extends up through the roof of thebody and ter- 10 minates over the hollow door posts 4. The tubing isconfined against Vmovement by suitable clamps II' attached at desiredspaced points in the vehicle body.

As best shown in-Figures 3 to 5, inclusive, a. 15

rock shaft I2 is journaled in each lock housing 5 and extends upwardlybeyond the top of its` p ost 4. A crank-arm I3 is secured to the upperend of each post l2, and the crank-arms are, in turn, connectedto theexible wires I0. As suggested 20 in Figure 2, the crank-arms I3 extendtoward one another. Thus, by operating the .handle 1, the rock shafts I2of the latches can be manipulated. The khousings 5 are rigidly securedin place within the hollow posts 4 in any preferred manner, andattaching plates I4 can be utilized for this purpose, as is clearlyshown in Figure 3 of the drawing. Within each lock housing is slidablymounted locking' bolts I5. These bolts extend through the opposite endwalls of the casings 5, a'nd through openings I6v in the opposite sidesof the center posts 4. The front and rear doors 2 and 3 of the vehiclebody are provided with keeper sockets I1 for receiving the bolts whenthe bolts 35 are in their projected position. The bolts I5 are formed onor secured to L-shaped slide plates I8 and I8 arranged within eachlock'housing 5. As shown in Figures 3 to 5, inclusive, the bolts I5 arecarried by the vertical angesZIl of the 40 L- shaped slide plates, andthe horizontal flanges of the slide plates lie on Opposite sides of theoperating cam 2I. 'I'his cam 2| is rigidly se- -curedto its rock shaft,and the ends thereof are adapted to bear against the vertical flanges 2045 The slide plates are provided with centrally disposed, longitudinallyextending slots 22 for. the rock shaft, and the ends of the cam 2Ilcarry oppositely directed pins 23 for engaging in slots vISI) 25 formedin the horizontal anges of theslide plates. Thus, the slide plates areactuated back and forth by the cam, and, obviously, when the cam is inthe position shown in Figure 4, the

slide plates are in their extended position, and M i inward pressure onthe bolts I! is resisted by the cam 2l.

As previously set forth, the rock shafts i! on oppositev sides of thevehicle body can be rocked back and forth by the actuating handle 'llocated in the drivers compartment, and, thus, by manipulating thehandle 1 the lock bolts can be moved into and out of locking positionwith the -1 by the opening of the doors through inadvertence or playingwith the latch handles is eliminated.

Changes in details may be made without departing from the spirit or thescope of my invention, but what I claim as new is: A

1. The combination with a vehicle body including a post and swingingdoors movable to a closed position against said post, of a lock for saiddoors carried by said post, including sliding bolts movable into and outof locking engagement with the doors, means for operating said bolts,including a rock shaft. extending through the post and terminatingbeyond one end thereof, an operating handle located adjacent the driversseat, a crank actuated by said handle, a crank on the shaft. and aexible cable connecting said cranks together. l

2. A door latch comprising a housing, L- shaped slides movable in thehousing having overlapping spaced body plates and rectangularlyextendingiianges, said flanges being arranged in spaced parallelrelation and disposed at the outer endsof the body plates, outwardlyextending bolts carried by the flanges, a rock shaft extending into thehousing, a doublear'med cam secured to the rock shaft and movable intoandout of engagement with the inner faces of the danses, said bodyplates also having connection with said cam including. pins carried bythe cam, and slots formed in the body plates receiving the pins, the camextending in a'stralght line-from one flange to the other when the boltsare projected.

3. A lock comprising a housing, a pair of L- shaped slides mounted insaid housing, each of said slides including a short vertical flange andan elongated body; plate, bolts secured to the flanges and projectingoutwardly from the outer faces of said flanges, a rock shaft extendinginto the housing, a double-armed cam secured tothe rock shaft andmovable into engagement withl the inner surfaces of the flanges, thebody plates having arcuate slots therein, and pins carried by the outerends of the arms of the cam received in said slots, the cam extendingina line from one flange to the other when the bolts are projected.
